Recombinant Human Holo-Transferrin
ART202S Recombinant Human Holo-Transferrin is a high-purity, animal-origin-free research-grade protein reagent independently developed and produced by Tonghua Anrate Biopharmaceutical. Manufactured through advanced recombinant expression technology, it completely avoids viral, TSE/BSE contamination risks associated with traditional plasma-derived transferrin. Supported by mature fermentation and purification processes, this product delivers excellent and stable performance, serving as a core essential raw material for serum-free cell culture, biopharmaceutical R&D, and cell expansion experiments.
As a fully iron-saturated holo-transferrin, this product features a stable iron supply system and acts as a direct iron source for cells without additional external iron supplementation. It is highly compatible with various cell culture systems and effectively solves common industry problems such as insufficient iron ions, low cell viability, and poor experimental repeatability in conventional culture systems.
Strict Quality Inspection Traceable Performance
Every batch undergoes comprehensive and rigorous testing, with measured indicators far exceeding general industry standards, ensuring strict and controllable quality:
✅Ultra-High Purity: The actual measured purity reaches 99.8% with extremely low impurities, minimizing experimental interference and ensuring high experimental accuracy.
✅ Low Endotoxin Level: Endotoxin content ＜0.5EU/mg, suitable for the culture of sensitive cells including stem cells, primary cells and immune cells.
✅ Stable Iron-Saturated System: Iron content is 0.16% with stable iron-binding status, continuously supplying iron ions for cells and promoting efficient cell proliferation.
✅ Excellent Physical Chemical Properties: Appears as red loose powder with superior solubility. The prepared solution is clear, transparent and pink. The pH value is 7.7, which fits the optimal range for cell culture and causes no irritation to cells.
✅ Complete Protein Structure: Positive result in Western blotting verification, ensuring complete biological structure and stable functional activity of the protein.
Core Product Advantages
1. High Biosafety: 100% animal-origin-free, no risk of blood-borne pathogen contamination, compliant with safety standards for high-end biopharmaceuticals and pre-clinical research.
2. Excellent Batch Consistency: Supported by Anrate’s large-scale standardized production system, the whole production process is strictly controlled with minimal batch-to-batch differences, ensuring stable and reproducible results for experiments and industrial production.
3. Efficient & Ready-to-Use: The inherent iron-saturated structure eliminates the need for secondary iron supplementation, simplifies medium formulation, and adapts to serum-free and protein-free culture systems, greatly improving R&D and production efficiency.
4. Stable & Easy Storage: Store at 2-8°C under conventional refrigeration. The lyophilized powder features high stability and long shelf life, reducing raw material loss and cost.
Application Scenarios
Widely applied in stem cell culture, immune cell expansion, CHO/HEK293 engineered cell culture, serum-free medium formulation development, biopharmaceutical research, and iron metabolism mechanism studies, covering high-end scientific research and bioproduction fields.
